WILLIAM J. HOLWAY, OF MANSFIELD, OHIO, ASSIGNOR OF TWO-THIRDS TO J. H. MOGINTY, OF SAME PLACE, AND 'ROBERT LOWE, OF WASHING- TON, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 673,77 5, dated May '7, 1901;

Application filed June 23, 1900. Serial No. 21,359. kNo model.)

To all wwwt it may concern:

Be it known that LWILLIAM J. HOLWAY, a citizen of the United States, residing at Manseld, in the county of Richland and State of Ohio, have invented a new and useful Soldering-Iron, of which the following is a specification.

The invention relates to improvelnents in self-heating soldering-irons.

The object of the present invention is to improve the construction of self-heating soldering-irons and to provide a simple and comparatively inexpensive one adapted to employ a solid copper head or soldering-tip and capable of heating the inner end of the same and of directing the flame into a cylindrical form and of concentrating it against the copper head or soldering-tip, whereby the latter will be practically enveloped in a thin sheet of name throughout the major portion of its length.

The invention consists in the construction' and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side elevation of a soldering-iron constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view on line 3 3 of Fig. 2. Fig. 4 is a similar view on line l Ll. Fig. 5 is a detail perspective view of the inner conical sleeve of the name-concentrating device.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a reservoir designed to contain gasolene or other suitable liquid-hydrocarbon fuel and arranged at the inner end of a hollow handle 2 and provided with a suitable iilling-opening 3 and cap 4, located at one side, as clearly shown in Fig. l of the accompanying drawings. The reservoir may be constructed in any suitable manner, and it communicates with a tube or pipe 5, which extends through the hollow handle 2, and the latter, which is preferably constructed of wood, may have a lining of asbestos or other cylindrical body 6, composed of a cylindrical v inner portion 7 and an outer annular portion 8, connected With the inner cylindrical portion by arms 9, 10, and 11. The arms 9 are solid, and the arms 10 and 1l are provided with passages, the passage of the arm 10 being in communicationyvith the pipe or tube 5 and being adapted to convey the liquid hydrocarbon to an annular generating-chamber 12, located within the outer annular portion 8 of Lthe body, at the outer end thereof. The passage ll, which is located at the opposite side of the body from the passage of the arm 10, extends from the annular gas generating chamber to a transverse passage 13, located at the inner cylindrical portion of the body and communicating with a centrally-arran ged burner 14E, extending outward from the inner cylindrical portion 7, as clearlyillustrated in Fig. 2 of the accompanying drawings. The inner portion of the outer annular part of the body is provided with an annular' series of apertures 15, which' are adapted to admit air into the space or chamber 16, and the bottom or inner wa1l17 ofthe chamber 16 is provided with a central opening and has an annular flange or wall 18 extending inward from the same and projecting into the space within the annular portion 8. By this construction air is admitted into the cylindrical body to support the combustion, and the discharge of the vapor is controlled by a needle-valve 19, having a stem extending through the tube 5 and the reservoir 1 and provided at its rear end with a handle 20. In order to retard the flow of the gasolene or other liquid fuel and render the same uniform, a spirally-coiled wire 22 is arranged Within the inner cylindrical portion of the body and is disposed around the central valve-socket 7, through which the valve-stem 21 is adapted to move.

The flame from the burner is concentrated and caused to envelop a copper soldering head or tip 24 by a device consisting of inner and outer conical sleeves 25 and 26,whicl1 and has a. concave inner face, and theshan-k i 30, which is threaded adjacent to the shoulder formed by the reduction of the tip, is extended inward beyond the screw-threads and projects into the inner tapering sleeve, practically to the inner end thereof, whereby the solid inner end or shank of the soldering-tip will be 'fheated 'rby the Aflame vof 'the fburnferbei fore it is spread by the concentrating :device and directed by thefsame upon theou'ter portion'o'f the soldering-tip. The inner .end oi the inner :tapered sleeve ,is providedfwith ex.- terior screw-'threads 3i, located ad-jacent to an .annular flange 32 .and adapted to @receive Vand fbe .engaged by interior screw-threads .33 of the outer tapered sleeve 26. The outer portion of the inner tapering sleeve is .pro-

Wlth an .annular series lof longitudinal The grooves 34fand an annfularseriesof apertures 35, arranged .at the inner ends of :the grooves and permitting :the darne to enter :the v,narrow annuinr space ybetween ethe inner and outeri` chews.

The you ter sleeve, which is imperl'or 1rate, extends a .considerable distance beyond .the -infnersleeve'and Visvadapted atoconcen'trate rthe .flame into athin sheet Vwhich envelops =the .major AVportion yof :the .solid copper solder.-
